988 | | * A PyArg_ParseTuple "converter" function |
989 | | * that handles filesystem paths in the manner |
990 | | * preferred by the os module. |
991 | | * |
992 | | * path_converter accepts (Unicode) strings and their |
993 | | * subclasses, and bytes and their subclasses. What |
994 | | * it does with the argument depends on the platform: |
995 | | * |
996 | | * * On Windows, if we get a (Unicode) string we |
997 | | * extract the wchar_t * and return it; if we get |
998 | | * bytes we decode to wchar_t * and return that. |
999 | | * |
1000 | | * * On all other platforms, strings are encoded |
1001 | | * to bytes using PyUnicode_FSConverter, then we |
1002 | | * extract the char * from the bytes object and |
1003 | | * return that. |
1004 | | * |
1005 | | * path_converter also optionally accepts signed |
1006 | | * integers (representing open file descriptors) instead |
1007 | | * of path strings. |
1008 | | * |
1009 | | * Input fields: |
1010 | | * path.nullable |
1011 | | * If nonzero, the path is permitted to be None. |
1012 | | * path.allow_fd |
1013 | | * If nonzero, the path is permitted to be a file handle |
1014 | | * (a signed int) instead of a string. |
1015 | | * path.function_name |
1016 | | * If non-NULL, path_converter will use that as the name |
1017 | | * of the function in error messages. |
1018 | | * (If path.function_name is NULL it omits the function name.) |
1019 | | * path.argument_name |
1020 | | * If non-NULL, path_converter will use that as the name |
1021 | | * of the parameter in error messages. |
1022 | | * (If path.argument_name is NULL it uses "path".) |
1023 | | * |
1024 | | * Output fields: |
1025 | | * path.wide |
1026 | | * Points to the path if it was expressed as Unicode |
1027 | | * and was not encoded. (Only used on Windows.) |
1028 | | * path.narrow |
1029 | | * Points to the path if it was expressed as bytes, |
1030 | | * or it was Unicode and was encoded to bytes. (On Windows, |
1031 | | * is a non-zero integer if the path was expressed as bytes. |
1032 | | * The type is deliberately incompatible to prevent misuse.) |
1033 | | * path.fd |
1034 | | * Contains a file descriptor if path.accept_fd was true |
1035 | | * and the caller provided a signed integer instead of any |
1036 | | * sort of string. |
1037 | | * |
1038 | | * WARNING: if your "path" parameter is optional, and is |
1039 | | * unspecified, path_converter will never get called. |
1040 | | * So if you set allow_fd, you *MUST* initialize path.fd = -1 |
1041 | | * yourself! |
1042 | | * path.length |
1043 | | * The length of the path in characters, if specified as |
1044 | | * a string. |
1045 | | * path.object |
1046 | | * The original object passed in (if get a PathLike object, |
1047 | | * the result of PyOS_FSPath() is treated as the original object). |
1048 | | * Own a reference to the object. |
1049 | | * path.cleanup |
1050 | | * For internal use only. May point to a temporary object. |
1051 | | * (Pay no attention to the man behind the curtain.) |
1052 | | * |
1053 | | * At most one of path.wide or path.narrow will be non-NULL. |
1054 | | * If path was None and path.nullable was set, |
1055 | | * or if path was an integer and path.allow_fd was set, |
1056 | | * both path.wide and path.narrow will be NULL |
1057 | | * and path.length will be 0. |
1058 | | * |
1059 | | * path_converter takes care to not write to the path_t |
1060 | | * unless it's successful. However it must reset the |
1061 | | * "cleanup" field each time it's called. |
1062 | | * |
1063 | | * Use as follows: |
1064 | | * path_t path; |
1065 | | * memset(&path, 0, sizeof(path)); |
1066 | | * PyArg_ParseTuple(args, "O&", path_converter, &path); |
1067 | | * // ... use values from path ... |
1068 | | * path_cleanup(&path); |
1069 | | * |
1070 | | * (Note that if PyArg_Parse fails you don't need to call |
1071 | | * path_cleanup(). However it is safe to do so.) |
